TABLE i-kTTACl-ZEJIENT FOR SEATS.

T 0 (iii whom it may concern:

Be it lrnown that l, "d rnl 1 l3. Cocoon, a citizen of the United Statesresiding at Chicago, in the county of Cool; and State of lllinois, haveinvented a new and useful Table ilttachnient tor heats of which thefollowing is a specification.

This invention relates to improvements in table-attachments for seats,ant pertains more especially to a vertically adjustabletable-attaclnnent which has its table adjustable at dillerent angles toa horizontal plane as required to render the table suitable for reading,drawing etc.

She object of this invention is to produce a highly practicaltable-attachment which 'cids interference with the requisite l: eeroomfor the occupant of the seat provided with the tab e-attachment.

Another object is to render said tableattacl'nnent transportable in aknock-down condition, and to facilitate the assemblage of its componentparts and tie manipulations requiren for a readjustment oi the table. 7

Another object is to render the table-attachment attractive inappearance and simple, strong and dura' is in construction.

lVith these objects in view, and to attain any other object hereinafterappearing, this invention consists in certain res 0t construction dcombinations and relative arrangement of parts, hereinafter described inthis specification, pointed out in the claims, and illustrated in theacconi aanying drawings.

In said drawings, Figure 1 partly in section and partly is a sine viewbroken away,

of a table-attachment embodyingrny invention. 2 is a horizontal sectiontaken Fig. 3 1s a vertialong the line 2 2, i. U cal section taken alontiie line 33, Fig. 1. Fig. 4 is side view or the upper portion of thetable attachrnent and shows the table at an angle to a horizontal plane,whereas in Figs. 1 and 3 the table is shown horizontal.

In said drawings A indicates two forwardly and rearwardly spacedsubstantially vertical members which are preferably of wood and renderedrigid in any approved manner with the framework of a seat and arrangedat t is forward end and right-hand side edge of the seat-proper B whichpreferably of wood and at said side edge has a forward extension 5 towhich the uprights Specification of Letters Patent.

A are glued or otherwise secured. One of the members A preferably formsaforward leg of the seat. The members A form a substantially verticallyarranged slideway engaged by a substantially vertically adj ustablestandard C which is preferably of wood and (see Figs. 2 and 3) engagesthe outer portion of the space between said slidewayforming members andoverlaps the laterally and outwardly facing sides of the said slide-"ay-forriing members.

Means for se tiring; the standard C to the members A in the desiredvertical adjustment of the standard are shown as coinprising a clampingbar 7, a bolt 8 and a nut 10, all relatively arranged and applied asshown more clearly in Fig. 2. Said clamping means are preferablyarranged lower than the seatproper l3. lhe bar 4 extends transversely ofand somewhat into the space between the members A and overlaps thelaterally and inwardly sides of said members. The bar 7 is shownprovided between the members A with two substantially horizontal andparallel laterally extending dowel-pins 12 which are spaced transverselyof the standard C and project into holes 13 formed in said standard. Thebolt 8 is sul stantially parallel with and arranged substantiallycentrally between said pins and has its head overlapping the laterallyand inwardly facing side of the bar 7 and has its shank extendinglaterally and loosely through said bar and laterally and loosely throughthe standard C and beyond the outer side of the standard. Preferably thestandard C has its portion which is penetrated or entered by the bolt 8and dowelpins 12 reinforced at its outer side by a wooden cleat 14;glued or otherwise secured to the remainder or body and forming a partof the standard. The shank of the bolt 8 extends or course through andoutwardly beyond said cleat. The nut 10 is screwed onto said shank atthe outer side of said cleat, and a washer 15 is interposed between saidnut and the cleat. Obviously a. manipulation of said nut as required towithdraw it from the washer l5 renders the standard 0 free to bereadjusted, and manipulation of said nut as required to press saidwasher against the standard results in clamping the standard against thelaterally and outwardly "facing sides of the slideway-forniing members Aand in causing the bar 7 to clamp the opposite sides of saidslideway-forming member, so as to secure the standard to said slideway-iorming members in the desired vertical adjustment of the standard.

At the inner side of the upper portion of the standard C (see Figs. 1and 3) is a bracket D consisting preferably of a laterally facingsubstantially vertical cast metal plate arranged in proximity to saidside of the standard. A suostantially horizontal bolt E, shown arrangedcentrally between the upper end portions of the slidewayforming membersA and substantially parallel with the hereinbefore mentioned bolt 8, hasits head arranged at the outer side of the standard (I and has its shankextending laterally through said standard and laterally through thelower end portion of the bracket l) and laterally through the lower endportion 16 of a substantially straightmetal brace G and inwardly leyondsaid brace. The brace G extends laterally or" and inwardly from theplate D and forwardly in relation to the seat-proper D. The bracket 1)and the brace E extend upwardly above the standard C, and H indicates adesk-top or table extending over and seated on the upper end of saidbrace and extending over and scared on the upper end of said bracket.

The standard C and the bracket l) are shown arranged under the table Hadjacent the right-hand side edge o1 the table, and said bracket issecured at its upper end, preferably removable by screws 17, to thetable. The brace G is shown secured at its upper end, by screws 13, tothe table H. The bracket D and the brace G are rotatably mounted on thebolt E, and a nut 20 is screwed onto the shank of said belt at thelaterally and inwardly facing side of the lower end portion 16 of thebrace. A washer 21 is shown extending circumferentially of the bolt Ebetween the bracket D and the standa "l C, and a washer 22 is showninterposed between the head of said bolt and the standard. The nut 20prevents displacement of the brace G oi'f the shank of the bolt E.Obviously the bolt E pivots the bracket D and the brace G to thestandard (1, and the lower end portion 16 01": the brace is seated,below said bolt, on a. flange 23 formed on said bracket and extendingcircumferentially of said bolt and embracing said end portion of andforming a seat for the brace.

' The table H (see Figs. 1 and 3) is provided over the standard C and atthe standard-facing side of the bracket D with a recess 25 extendingforwardly and rearwardly of the table and engaged by a metal section itwhich is secured by screws 24: to and forms a part of the table. Thestandard 0 has a curved top which is concentric relative to the pivotalbolt E, and the standard is shown provided at said top and centrallybetween its sides with an upwardly projecting tongue 27 which extendsfrom the forward edge to the rear ed e of the standard and circumfer-'entially of said bolt and is concentric relathe under side or bottom ofthe section it.

The standard C is provided at each side of its tongue 27 with a curvedtop surface 29 extending from the forward edge to the rear edge of thestandard and arranged concentrically relative to the pivotal bolt E. Themetal section it is seated at the sides of its groove 28 on the topsurfaces 29 of the standard. Hence the table has bearing at each side ofsaid groove on the standard. The tongue 27 and the side walls of thegroove 28 coiiperate in preventing displacement of the table laterallyof the standard. By the construction hereinbefore described it will beobserved that the metal section it straddles the tongue 27 on thestandard, and the tongue-straddling portion of said section extendsfarther circuinterentially oi": the pivotal bolt E than the top of thestandard and covers said tongue and the surfaces 29 in any adjustment ofthe table circumferentially of the pivotal bolt E.

Means for securing the bracket D, and consequently the table H, in thedesired adjustment circum'terentially of the pivotal bolt E are providedand arranged between said bolt and the upper extremity of the standard Gand preferably farther from said bolt than from said extremity and (seeFigs. 1 and 3) comprise a bolt 31 and a nut 32 which is in the form of ahand-wheel. The bolt 31 is substantially parallel with the pivotal boltE and has its head arranged at the laterally and inwardly facing side ofthe bracket l) and has its shank extending through a curved slot (Zformed in the bracket and laterally and loosely through the standard Cand beyond the outer side of the standard, and the nut 32 is screwedonto said shank at said side of the standard. A washer 33 is interposedbetween the nut 32 and the standard (I. A.washer 34 extendscircumferentially of the bolt 31 between the standard C and the bracketD, and a washer 35 is interposed between said bracket and the head ofsaid bolt. The slot cl is arranged concentrically relative to thepivotal bolt E. Obviously a manipulation of the nut 32 as required torender the bracket D free to be readjusted permits readjustment of thetable H and brace G circumterentially of said bolt, and the bracket andconsequently the table are secured to the standard in the desiredadjustment upon a manipulation of said nut as required to clamp thebracket to the standard. The bolt 31 and one end wall of said slotcooperate in limiting the adjustment of the table circumferentially ofthe pivotal bolt E in one direction, and the other end wall of said slotand said bolt cooperate in limiting the adjustment of the tablecircumferentially of the said bolt in the opposite direction. Therelative arrangement of the parts is preferably such that when the tableis in a substantially horizontal position the slot cl has its end wallwhich faces in a forward direction relative to the seat-proper l3cooperating with the clamping bolt 31 in limiting movement of the tablein said direction. Fig. l shows the table adjusted at an angle to ahorizontal plane.

By the construction hereinbefore described it will be observed that notonly is a standard C arranged at the forward end and one side of andrigid with a seat, and. a table H provided forward of and above saidseat and adapted to be supported wholly from said standard, but that abracket D is arranged at the laterally inwardly facing side of thestandard and extends downwardly from the under side of the table, thatthe table extends over the upper end of and is rigidly secured to saidbracket, that the table is also rigidly secured at a point spacedlaterally inwardly from the upper end of the bracket to and extends overthe upper end of a diagonal brace G which is arranged wholly under saidtable at the laterally inwardly facing side of the bracket and extendsfrom said point downwardly and toward the lower end of the bracket andhas its lower end arranged opposite and next said side of the bracket,that the axes of the brace and bracket are therefore coincident, thatthe bracket and brace are adj ustable circumferentially of the axis ofsaid pivotal member, that the table is therefore adjustablecircumferentially of said pivotal member, that means are provided forsecuring the bracket to the standard in the desired adjustment of thetable circumferentially of said pivotal member, that the upper end ofthe standard has the contour, dimensions and arrangement required topermit readjustment of the table circumferentially of said pivotalmember and to permit the table to have bearing on said end of thestandard, that the clamping means for clamping the bracket to thestandard in the desired adjustment of the table circumferentially ofsaid pivotal member are arranged between the table and the axis of thebracket, that the bracket is provided under and next the lower end ofthe brace with a flan e extendin circumferentiall of and D C! Jconcentric in relation to said pivotal memher, and that the relativearrangement of the parts is such that the hereinbefore stated objects ofmy invention are successfully attained.
